Hi all,

How do you calculate how many ports are used on a T1 and OPC card? I'm trying to calculate the limit that my system can handle. YOur help will greatly appreciated.

Thank you ahead of time.

In DB Programming, look up System\Cabinets\(your T1 card)\T1 circuits. That will tell you how many you have.

I'm not sure what you mean about ports on the OPC.

Thanks for replying dfleschute.

I was told on my last posting that OPC card also used up ports, therefore I'm trying to figure out how can I calculate the OPC card towards the limitation of port on my system.

Here's the link to the last posting.

The options card does not count towards your "ports" but it does take a card slot.
The OPC card provides DSP resources to provide speakerphone capability, conference circuits, caller ID and DTMF... There are a max of 4 DSP's on an options card, so you need to be very aware of all the resources you are using on a system this large.

It looks ( if I counted right) that you have 2 open card slots remaining, but your problem is your system is maxed out. You are presently carded for 12 more time slots than you have capacity for. Meaning you will not be able to make everything hot.. Your CPU has a 128 port capacity and as carded you would require 140 to make everything hot.

You will need to Upgrade to a CPU 256 to go any further in your growth. On 6.0 this requires a physical hardware change.(Pulling out the 128 and installing a 256)

8.0 software moved to Licensing and all CPU's could be upgraded by simply downloading a larger license. Unless you are really wanting to spend some money to overhaul the system, finding a 6.0 CPU256 is your best bet.

a T-1 Circuit is 24 channels, if you are using a full T-1 you are using 24 time slots. You may need to check with your service providers to determine how many channels on each T-1 you are using.


I hope this info helps.

Hey Bob,

Thanks, this is very helpful.You're correct I have two additional slot left. I also have a full T1 and from what I recall my provider said we are using 24 lines. If I have two T1 cards. Does this mean I have two full T1?

I'm not sure if I'm understanding this correctly. Sorry, I still trying to understand the hardware side of the system.

You said, "8.0 software moved to Licensing and all CPU's could be upgraded by simply downloading a larger license." If I take this approach. Do I still have to installed a CPU256 card or do I simply download the 8.0 software to upgrade my existing CPU. If I'm upgrading my current CPU to 8.0 software without installing a CPU256 card. Will this allow me to install more line.

What does this mean? "You are presently carded for 12 more time slots than you have capacity for. " Does this mean my system is capable of handling 140 hot ports maximum and right now I'm at 128; which is 100% capacity.

Also, What if the system is showing that a phone number is assigning to specific port, but the port is not hot. Will this still utilize the CPU? If it's not utilize, can I use the port without exceeding capacity because my predecessor have already pre assign the port for future use. I guess I'm trying to asks is the calculation for the capacity of the system is based on pre-configure ports even if it's not in use because we only know by the configuration on the system and not physically test.

Sorry for the number of question. Greatly appreciated if you can provide some assistance.

Many thanks.

Yes, two T1 cards would be 48 channels.
As far as the CPU goes, the newer systems use a CPC card. This replaces the different size CPU cards. You just need to get the appropriate licensing with it from your dealer. In your case you would need a CPC card with a 256 license, and a higher software version. Or you could just get a CPU 256 with version 6.0 software. Either way I would contact a dealer in your area.
The CPU 128 that you currently are using has a maximum of 128 ports in use. If you are using 140 out of 128 possible, then you are over 100 percent utilization.

Jeff,

Great information.

Thanks.

Jeff,

Is CPC card compatible with CPU cards? I have two Intertel system.

What's the maximum license can be purchase on CPC before the card is cap out?


Thanks,
Sang

With the CPC, the max is 256. After 256 ports, you would use a CPU 512 card with an ethernet port, and a CPS server.
I am not sure about being compatible with the CPU, I assume you have the two systems networked together?

Yes, The two system is network together through a T1 point to point connection. Two location is 500 miles apart. One has a CPU64(max out) and the other have a 128(max out).

I was planning to install a CPU256 in replace of 128 and take the 128 and replace with the 64. How much does the card usually run and hard is it to install the card? As far as I know removing and installing and restore the backup file.

Also, this is on a different subject. Right now I am trying to find out which DID number is assign to a SLC port/extension. How can figure out the number assign?

Thanks.
